Description

  The present invention relates to a storage shelf used in an office, home, warehouse, store, or the like, or a display shelf used in a store, and relates to an assembly shelf that can be assembled and disassembled without tools.

  Conventionally, assembling shelves obtained by assembling a shelf member and a support column can be roughly divided into a pipe-shaped support and an L-shaped support. As an L-shaped one, there are known ones in which a protrusion-like locking portion of a shelf member is inserted into a mounting hole of a column (Japanese Patent Laid-Open Nos. 10-1667075 and 10-165233, Japanese Patent Laid-Open No. 2008-212414 publication). Further, there is known an assembly shelf in which a rectangular shelf plate formed by bending steel plates on four L-shaped angle columns is assembled using L-shaped fixing brackets and bolts (Japanese Patent Laid-Open No. Hei 9). -238758). These assembly shelves can be provided at low cost. Moreover, the assembly shelf of JP-A-10-167075 is convenient because the shelf member can be easily detached.

  On the other hand, when the support is pipe-shaped, a plurality of annular locking grooves are formed on the outer peripheral surface at predetermined intervals in the longitudinal direction and formed on the inner peripheral surface that is locked to the locking groove of the support. And a shelf member having a shape in which the diameter of the taper rib is gradually expanded as the outer shape is directed downward, and a shelf member in which a ring inserted into the outer peripheral surface of the taper sleeve is fixed to four corners. An assembly shelf is known (Registered Utility Model Publication No. 3057990). The assembly shelf of the registered utility model publication No. 3057990 is good in appearance and easy to assemble because, for example, when two shelf members are connected in the longitudinal direction, one support column can be shared.

  However, the assembly shelf using the L-shaped angle has a locking projection on the shelf member, which is inferior in design and has a risk of damaging an operator's hand during assembly. In addition, bolts for L-shaped fixing brackets are inconvenient because a bolting tool is required separately during assembly. In addition, the assembly shelf of the registered utility model publication No. 3057990 is located above the intermediate shelf member when it is desired to change the position of the intermediate shelf member in the assembly shelf having a plurality of upper and lower stages (hereinafter, also referred to as “centering operation”). It was necessary to remove the shelf members in For this reason, although the assembly is simple, the hollowing operation is inconvenient and the hollowing cannot be substantially performed.

  Accordingly, an object of the present invention is an assembly shelf using an L-shaped angle-type support column, in which there is no protrusion on the shelf member, no tool is required for assembly, and an assembly shelf that can be hollowed out is provided. It is to provide.

  That is, the present invention solves the above-described conventional problems, and has a shape including an L-shaped cross section, and a regular or irregular interval in the longitudinal direction on a plate-like portion on one side constituting the L-shape. And a pair of support parts that are foldably joined by a hinge, and a protrusion is formed on the back surface of one support part, and the other support part has the An engagement hole is formed in which the tip of the projection is fitted, and the projection is passed through the engagement through-hole of the column so that the tip of the projection and the engagement hole are engaged to hold the plate-like portion from the side. And a shelf member including a coupling member that is a tapered surface in which the outer peripheral side surfaces of the pair of support portions gradually expand downward, and an engagement portion that engages with the coupling member. The assembly shelf characterized by having these.

  Further, the present invention provides the assembly shelf, wherein the support column has an L-shaped cross-sectional shape, a T-shaped cross-sectional shape, a cross-shaped cross-sectional shape, or a channel shape.

  Further, the present invention provides the assembly shelf, wherein the coupling member is made of resin and the hinge is thin.

  Further, according to the present invention, the support column has an L-shaped cross-sectional shape, and a plurality of second engagement through holes are formed at regular or irregular intervals in the longitudinal direction on the plate-like portion on the other side constituting the L-shape. The assembly shelf is provided.

  According to the assembly shelf of the present invention, there is no protrusion on the shelf member, and no assembly tool is required for assembly. In addition, if there is a space between the intermediate shelf member and the upper shelf member that allows the intermediate shelf member to be inclined and pulled out to the front, the position change of the intermediate shelf member in the assembly shelf having a plurality of upper and lower stages can be changed. It is possible to remove and reattach only the intermediate shelf member without changing the shelf member.

  Next, the assembly shelf in the first embodiment of the present invention will be described with reference to FIGS. The assembly shelf 10 is an assembly of the support column 1, the coupling member 2, and the shelf member 3. The support column 1 has a shape including an L-shaped cross section, for example, an L-shaped cross-sectional shape, a T-shaped cross-sectional shape, a cross-shaped cross-sectional shape, or a channel shape (a U-shaped cross-sectional shape) having a predetermined length (height). It is. If the support | pillar 1 is such a shape, while being excellent in intensity | strength and installation stability, it can provide at low cost. In addition, the support | pillar 1 is the meaning which excludes hollow tubes, such as a pipe.

In the column 1, a plurality of engagement through-holes 11 are formed at regular or irregular intervals in the longitudinal direction (height direction) in a plate-like portion that is one side portion that constitutes an L shape and has a side end portion. The The plate-like portion having one side that constitutes the L-shape and having the side end portion is one of two plate-like portions constituting the L-shape in the L-shaped cross-sectional shape, and in the T-shaped cross-sectional shape. , Any of three plate-like portions extending in three directions from the intersection of the horizontal bar and the vertical bar constituting the T-shape, and in the cross sectional shape, 4 from the intersection of the horizontal bar and the vertical bar constituting the cross. It is one of the four plate-like portions extending in the direction, and in the channel shape (C-shaped cross-sectional shape), it is one of the two plate-like portions facing each other. The irregular interval between the engagement through holes 11 is, for example, when the two engagement through holes 11 through which the protrusions of the coupling member 2 pass are set as one set, the pitch between the sets is p ₁ or p ₂ is continuous, or is formed by repeating them arbitrarily or alternately (FIG. 30). Note that the pitch p ₁ is different from the pitch of the two engagement through holes 11.

  In the support column 1, the engagement through hole 11 is a portion through which the protrusion 22 of the coupling member 2 is passed. Moreover, the installation position of the coupling member 2, ie, the installation position of the shelf member 3, can be arbitrarily set by forming in multiple in a longitudinal direction. The inner diameter of the engagement through hole 11 may be the same as or slightly larger than the outer diameter of the protrusion of the coupling member 2. If the engagement through-hole 11 and the projection 22 of the coupling member 2 are tightly fitted, it is difficult to fit, and if the fit is too loose, the installation stability of the shelf member 3 is deteriorated. Further, the distance from the side end surface of the engagement through hole 11 is determined by the relationship with the projection position of the coupling member 2.

  The coupling member 2 is attached to the support column 1 and supports the shelf member 3. The coupling member 2 is made from metal, resin, glass, carbon, or a composite thereof. Among these, resin-made ones are preferable in that no metal sound is generated during assembly and the assembly is easy. As the resin, engineering plastics such as polyacetal resin, polyamide resin, acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS resin), epoxy resin, phenol resin, and polycarbonate resin can be used. These synthetic resins are excellent in impact resistance, wear resistance, and chemical resistance. The resin may further contain reinforcing fibers such as glass fibers and carbon fibers.

  As shown in FIGS. 3 and 4, the coupling member 2 is a pair of support portions 21 a and 21 b that are foldably joined by a hinge 24, and a protrusion 22 is formed on the back surface of one support portion 21 a. The other support portion 21b is formed with an engagement hole 23 into which the tip of the protrusion 22 is fitted. The number of protrusions 22 is not particularly limited, but is preferably 2 or 3 in the vertical direction. When the number of the protrusions 22 is one, the support strength is weak, and when the number is four or more, the longitudinal length of the coupling member 2 becomes large, and the material is wasted. FIG. 28 shows a coupling member when there are three protrusions 22.

  The shape of the protrusion 22 and the shape of the engagement hole 23 are not particularly limited as long as the two fit tightly. For example, as shown in FIG. One provided with a locking portion 223 that protrudes short in a direction perpendicular to the axial direction of 222. The locking portion 223 is inclined downward toward the tip end side of the cylindrical protrusion 222. Further, the number of the locking portions 223 is one in this example, but may be two provided at a symmetrical position, or may be three or four. By forming the locking portion 223, the fitting strength is improved. Further, the base end side of the cylindrical protrusion 222 is a diameter-enlarged portion 221. Thereby, it can insert in the engagement through-hole 11 of the support | pillar 1 without a gap, without damaging the cylindrical projection part 222. FIG. The tip end angle of the cylindrical protrusion 222 is rounded. Thereby, it is easy to fit in the engagement hole 23, and there is no injury. The protrusion 22 is not limited to the form as shown in FIG. 3. For example, an annular diameter-enlarged portion (not shown) having an outer diameter slightly larger than the outer diameter of the cylindrical protrusion is provided on the distal end side of the short cylindrical protrusion. It may be. The annular enlarged diameter portion 222 has the same effect as that of the locking portion 223.

  As shown in FIG. 8, the engagement hole 23 is a through hole, and a first hole portion 231 having an inner diameter that is the same as or slightly larger than the outer diameter of the cylindrical protrusion 222, It is an outer portion of the through hole, and includes a second hole portion 232 having an inner diameter slightly larger than the inner diameter of the first hole portion 231 continuous with the first hole portion 231. That is, the engagement hole 23 is a hole having a step difference in which the hole diameter of the outer hole is larger than the hole diameter of the inner hole. As a result, the engagement between the engagement hole 23 and the protrusion 22 needs to be strongly fitted, but once fitted, it is difficult to come off.

  The pair of support portions 21a and 21b is installed so that the projection 22 is passed through the engagement through-hole 11 of the support column 1 and the tip portion 222 of the projection 22 and the engagement hole 23 are engaged to hold the plate-like portion 1a from the side. Is done. At this time, the protrusion 22 and the engagement hole 23 are slightly crushed by the first hole 231 of the engagement hole 23 by pinching the pair of support portions 21 a and 21 b with a hand and slightly pushing it. The second hole 232 is fitted into the second hole 231 beyond the first hole 231. Such fitting increases the fitting strength, and can be done by hand without tools when removing the fitting. In addition, after the protrusion 22 and the engagement hole 23 are fitted, the protrusion 22 remains inside the engagement hole 23, and the tip of the protrusion 22 does not protrude to the outside opposite to the entrance of the engagement hole 23. Absent. If the tip of the protrusion 22 protrudes outward from the engagement hole 23, the engagement with the shelf member side engagement portion 4 becomes impossible. In addition, although the engagement hole 23 is a through-hole in this example, it is not limited to this, A non-through-hole may be sufficient. The number of engagement holes 23 is determined by the number of protrusions 22 installed.

  In the coupling member 2, the pair of support portions 21a and 21b are substantially plate-like bodies each having a predetermined thickness in this example (FIGS. 3 and 4). The coupling member 2 is an integral member in which these two substantially plate-like bodies are joined by a hinge 24. The hinge 24 is preferably a thin plate shape having a predetermined width made of resin or metal, a strip shape, or a string shape having a predetermined length. If the hinge 24 is a thin plate having a predetermined width, a band, or a string having a predetermined length, the pair of support portions 21a and 21b are integrated with each other when not in use, and one of them is attached without being lost. At this time, the contact surfaces with the plate-like portion 1a can be opposed to each other so as to be parallel to each other.

  The outer peripheral side surfaces 25 and 26 of the pair of support portions 21a and 21b are tapered surfaces that gradually expand downward. Thereby, if the shelf member side engaging portion 4 is fitted, the downward movement of the shelf member 3 can be restricted by the contact of the tapered surfaces, and the coupling member 2 in which the shelf member 3 is fixed to the column 1. Can be fixed. When the pair of support portions 21a and 21b is a plate-like body, the outer peripheral side surfaces 25 and 26 refer to the two surfaces 26 and 26 of the pair of support portions 21a and 21b, and preferably further include the side surfaces 25 and 25. Say four sides. Even if the tapered surfaces gradually expanding downward are the two outer peripheral side surfaces 26 and 26, a sufficient supporting effect is exhibited. In this example, the side surface 25 having the hinge 24 has a smaller taper forming area than the side surface 25 having no hinge 24 that faces it. Even if the taper forming area is small, a sufficient supporting effect is exhibited. If the taper of the outer peripheral side surfaces 25, 25 and 26, 26 is approximately 2 to 3 degrees, sufficient tightening strength can be imparted. The contact surfaces of the pair of support portions 21 a and 21 b with the plate-like body are flat surfaces except for the protrusions 22 and the engagement holes 23. Thereby, the adhesiveness to the plate-shaped part of the support | pillar 1 improves.

  The shelf member 3 includes an engaging portion 4 that engages with the coupling member 2. In the shelf member 3, the formation position of the engaging portion 4 is not particularly limited, but approximately four corners are preferable. By forming the engaging portions at the four corners, the area (mounting area) formed by the four columns 1 can be increased, and the installation of the assembly shelf 10 is stabilized. The shelf body portion of the shelf member may be either a board shape or a mesh shape. The shape of the shelf member 31 is not particularly limited, but is usually rectangular in plan view.

  The engaging portion 4 has an engaging main body portion 411 that penetrates up and down and has an inner shape corresponding to the outer shape of the coupling member 2. That is, as shown in FIG. 12, the engagement main body portion 411 has a rectangular shape in plan view, and the end portion side has an opening 412 having a width slightly larger than the thickness of the plate-like portion 1a. Thereby, it can assemble with respect to the support | pillar 1 with which the coupling member 2 was mounted | worn by moving the engaging part 4 of the shelf member 3 from the upper direction to the downward direction.

  Inner walls 413 and 413 extending in parallel with the longitudinal direction of the shelf member 3 of the engagement main body 411 are portions in contact with the outer peripheral side surfaces 26 and 26 of the pair of support portions 21a and 21b of the coupling member 2, as shown in FIG. It is a tapered surface similar to the outer peripheral side surfaces 26, 26. Further, the inner walls 414, 414 extending in parallel with the short direction of the shelf member 3 of the engagement main body 411 have outer peripheral side surfaces 25, 25 of the pair of support portions 21a, 21b of the coupling member 2, as shown in FIG. And is a tapered surface similar to the outer peripheral side surfaces 25, 25. The height of the engagement main body 411 may be the same as or slightly larger than the height of the coupling member 2. Thereby, after the shelf member 3 is fitted in the coupling member 2, the coupling member 2 is not visible from the outside, and the design is excellent.

  Next, a method for assembling the assembly shelf 10 of the present invention will be described. First, the coupling member 2 is attached to a predetermined position of the column 1 (FIG. 5). That is, the protrusions 22 and 22 of the support portion 21a of the coupling member 2 are passed through the engagement through holes 11 and 11 formed in the support column 1 (FIGS. 6 and 8). At this time, the tip portions of the protrusions 22 and 22 pass through the engagement through holes 11 and 11 and protrude from the plate-like portion 1 a of the support column 1. Next, the pair of support portions 21 a and 21 b are firmly clamped by hand, and the tip end portion of the protrusion 22 is fitted into the engagement hole 23. At this time, the engaging portion 223 of the protrusion 22 is pushed in while slightly crushing the first hole portion 231 of the engaging hole 23 and fits into the second hole portion 232 beyond the first hole portion 231. Can be experienced (FIGS. 7 to 11). Other coupling members 2 are attached to the support column 1 in the same manner.

  Next, the engaging portion 4 of the shelf member 3 is engaged with the coupling member 2. As shown in FIG. 2, the engaging method is to move the shelf member 3 from the upper side to the lower side with respect to the coupling member 2, thereby engaging the engaging portion 4 of the shelf member 3 with the coupling member 2. Combine. The opening width of the opening 412 of the engaging portion 4 is larger than the thickness of the plate-like portion 1 a of the support column 1, and the lower end opening shape of the engaging main body portion 411 of the engaging portion 4 is the upper end of the coupling member 2. Since it is larger than the shape, the coupling member 2 enters the engagement main body 411. At this time, the tapered surfaces 26, 26 on the outer peripheral side surface of the coupling member 2 and the tapered surfaces 413, 413 on the inner peripheral surface of the engagement main body 411 are contacted, and the other tapered surface on the outer peripheral side surface of the coupling member 2. 25 and 25 and the taper surfaces 414 and 414 on the other inner peripheral surface of the engagement main body 411 are in contact with each other, so that both are strongly tightened (FIGS. 15 to 17). Thus, both the coupling member 2 and the shelf member 3 can be attached to the support column 1 without an attachment tool. Further, the shelf member 3 does not have an engaging projection, so that it is not injured when handled by an operator.

  A method of attaching the lowest shelf member 3a and the intermediate shelf member 3b in FIG. 1 will be described. The method of attaching the coupling member 2 to the support 1 is the same as described above. Next, the shelf member 3 is attached to the coupling member 2. At this time, for example, in the case of the lowest shelf member 3a, between the lowest shelf member 3a and the intermediate shelf member 3b, in the case of the intermediate shelf member 3b, the intermediate shelf member 3b and the uppermost shelf member 3a. The shelf member 3 in an oblique posture is inserted from the front into the space between the shelf members 3c and tilted so as to be in a horizontal posture. At this time, the plate-like portion 1a of the support column 1 is placed in the opening 412 of the engagement portion 4. Take a horizontal posture through. Next, the shelf member 3 (3a or 3b) is attached to the coupling member 2 in the same manner as described above. In addition, when there is no space in which the shelf member 3 made into the slanting posture enters, it may be attached before attaching the upper shelf member 3. In this way, the assembly shelf 10 of FIG. 1 is completed.

  Next, a method for disassembling the assembly shelf 10 will be described. In order to remove the shelf member 3 from the assembly shelf 10, the shelf member 3 is sequentially removed from the upper shelf member 3. To remove the shelf member 3, the shelf member 3 may be pushed upward, disengaged from the coupling member 2, and taken out from above the column 1. In addition, in the assembly shelf 10 shown in FIG. 1, when removing only the intermediate shelf member 3b, there is a space between the intermediate shelf member 3b and the upper shelf member 3a that allows the intermediate shelf member 3b to be inclined and pulled forward. Yes. That is, the hollowing of the intermediate shelf member 3b may be performed by pushing the intermediate shelf member 3b upward and releasing the fitting with the coupling member 2 so as to be inclined and then pulling it forward (FIG. 29). . The positional relationship between the L-shaped cross-sectional column 1 and the shelf member 3 is not limited to that shown in FIG. 17, and the other side constituting the L shape (a plate on which the engagement through hole 11 is not formed). The method of extending the shape portion 1b may be in the outer direction opposite to the inner direction in FIG.

  According to the assembly shelf 10 of the present example, the shelf member 3 has no protrusions, does not hurt human hands during assembly, and does not require an assembly tool. Moreover, since the support | pillar 1 is L-shaped cross-sectional shape (L-shaped angle), installation stability is good and can be provided cheaply. If there is a space between the intermediate shelf member and the upper shelf member, the intermediate shelf member is inclined and pulled out to the front, the position change of the intermediate shelf member in the assembly shelf having a plurality of upper and lower stages can be changed to other shelf members. As it is, only the intermediate shelf member can be removed and reattached.

  Next, an assembly shelf according to a second embodiment of the present invention will be described with reference to FIGS. 18 to 20, the same components as those in FIGS. 1 to 17 are denoted by the same reference numerals, description thereof is omitted, and different points are mainly described. That is, in the assembly shelves 10a to 10c in the second embodiment, the difference from the assembly shelf 10 in the first embodiment is the shape of the column 1. That is, as shown in FIG. 18, the support column 1a of the assembly shelf 10a has a T-shaped cross section, and is formed by forming an engagement through hole in the plate-like portion 11a on one side of the horizontal bar constituting the T-shape. is there. In addition, the vertical bar which comprises T character is extended in the inner side direction of the shelf member 3. As shown in FIG. Further, as shown in FIG. 19, the column 1b of the assembly shelf 10b has a cross-sectional shape, and is formed by forming an engagement through hole in the plate-like portion 11b on one side of the horizontal bar constituting the cross. Further, as shown in FIG. 20, the support column 1c of the assembly shelf 10c has a U-shaped cross-sectional shape (channel shape), and an engagement through hole is formed in the plate-like portion 11c on one side of the horizontal bar constituting the U-shape. Formed. The assembly shelves 10a to 10c all have the same effects as the assembly shelf 10. In addition, the plate-like part 111c on the other side facing the plate-like part 11c on one side of the horizontal bar constituting the U-shape is an outer side of the shelf member 3 and a side extending in the longitudinal direction of the shelf member 3. Parallel.

  Next, the assembly shelf in the 3rd Embodiment of this invention is demonstrated with reference to FIGS. 21 to 25, the same components as those in FIGS. 1 to 17 are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described. In other words, the assembly shelves 10 d to 10 h in the third embodiment are different from the assembly shelf 10 in the first embodiment in the number of coupling members 2 and shelf members 3 used and the shape of the columns 1. That is, the assembly shelf 10d connects the two shelf members 3 with one support column 1d (FIG. 21). The support column 1 has an L-shaped cross-sectional shape, and an engagement through hole 11 is formed in any of the plate-like portions 1a and 1b on two sides constituting the L shape. That is, the column 1a is formed by forming a plurality of second engagement through holes 11 at regular or irregular intervals in the longitudinal direction also on the plate-like portion 1b on the other side constituting the L-shape in the column 1. is there. In addition, the vertical bar which comprises the L character of the support | pillar 1d is a little longer than the vertical bar which comprises the L character of the support | pillar 1. Thereby, connection of the two shelf members 3 is attained. Moreover, in the assembly shelf 10d, the directions of the engaging portion 4 of the shelf member 3 and the coupling member 2 are orthogonal to each other due to the L-shape of the support column 1d.

  The assembly shelf 10e connects the two shelf members 3 with one support column 1e (FIG. 22). The support column 1e has a shape in which the flange portion 11e extends outwardly from the ends of a pair of opposite sides of the U-shaped cross-sectional shape in a direction perpendicular to the pair of sides, and is associated with the plate-like portion related to the flange portions 11e and 11e. A combined through hole 11 is formed. Thereby, connection of the two shelf members 3 is attained. In the assembly shelf 10e, the direction of the engaging portion 4 and the coupling member 2 of the shelf member 3 is such that the flanges 11e and 11e of the support column 1e extend 180 degrees on the opposite side, and the two assembly shelves extend in the longitudinal direction. Continuous connection.

  The assembly shelf 10f connects the two shelf members 3 with one support column 1f (FIG. 23). The support column 1f has a crank shape in which a flange portion 11f extends outward from an end of a short side constituting an L-shape, and engages and penetrates into a plate-like portion related to two side portions 11f and 11f that are parallel to each other. A hole 11 is formed. Thereby, connection of the two shelf members 3 is attained. In the assembly shelf 10f, the direction of the engaging portion 4 and the coupling member 2 of the shelf member 3 is such that the two side portions 11f and 11f of the support column 1f extend 180 degrees opposite to each other, and the two assembly shelves are in the longitudinal direction. It becomes a continuous connection to.

  The assembly shelf 10g connects the two shelf members 3 with one support column 1g (FIG. 24). The strut 1g has a T-shaped cross-sectional shape, and is formed by forming engagement through holes 11 in plate-like portions 11g related to the horizontal bars constituting the T-shape. Thereby, connection of the two shelf members 3 is attained. In the assembly shelf 10g, the direction of the engaging portion 4 and the coupling member 2 of the shelf member 3 is such that the two plate-like portions 11g and 11g of the support column 1g extend 180 degrees opposite to each other, and the two assembly shelves are long. It becomes a continuous connection in the direction.

  The assembly shelf 10h connects the two shelf members 3 with one support column 1h (FIG. 25). The column 1h has a cross-sectional shape, and is formed by forming engagement through holes 11 in two plate-like portions 11h and 11h related to a horizontal bar constituting the cross. Thereby, connection of the two shelf members 3 is attained. In the assembly shelf 10h, the direction of the engaging portion 4 and the coupling member 2 of the shelf member 3 is such that the two plate-like portions 11h and 11h of the column 1h extend 180 degrees opposite to each other, and the two assembly shelves are long. It becomes a continuous connection in the direction. The assembly shelves 10d to 10h all have the same effects as the assembly shelf 10.

  Next, an assembly shelf according to the fourth embodiment of the present invention will be described with reference to FIGS. 26 to 27, the same components as those in FIGS. 1 to 17 are denoted by the same reference numerals, description thereof is omitted, and different points are mainly described. That is, the assembly shelf in the fourth embodiment is different from the assembly shelf 10 in the first embodiment in the shape of the engaging portions of the coupling member 2 and the shelf member 3. In the coupling member 2a, the pair of support portions have a semi-conical shape with a half appearance, and in a mounted state, the plan view has a circular shape. Moreover, the outer peripheral side surface of a pair of support part 21g is a taper surface which expands gradually toward the downward direction. The engaging portion of the shelf member 3 has a shape corresponding to the coupling member 2a, that is, the shape of the engaging main body portion is circular in plan view. The assembly shelf provided with the coupling member 2a has the same effects as the assembly shelf 10.

  In the present invention, various modifications can be adopted in addition to the above embodiment. The protrusions of the coupling member are not limited to the short cylindrical protrusions described above, and may be elliptical cross-sectional protrusions, rhombic cross-sectional protrusions, and irregularly-shaped cross-sectional protrusions. In this case, the shape of the engagement hole into which the protrusion fits may be a shape that allows a slightly stronger fit. Moreover, the annular diameter-enlarged portion formed on the protrusion may be appropriately provided with a notch in the circumferential direction.

  According to the present invention, there is no protrusion on the shelf member, no assembly tool is required, and it is safe for the operator during assembly. In addition, if there is a space between the intermediate shelf member and the upper shelf member that allows the intermediate shelf member to be inclined and pulled out to the front, the position change of the intermediate shelf member in the assembly shelf having a plurality of upper and lower stages can be changed. It is possible to remove and reattach only the intermediate shelf member without changing the shelf member.
